Power Splitter

The power splitter cable has a single RJ45 female connector on one end.

Cable

All eight pins on this connector are connected, either to the power or to

 

data.

 

On the other end, the cable is split into two portions. The power plug

 

carries the –24VDC (and returns) from pins 4, 5, 7, and 8. The RJ45

 

carries the data signals (transmit and receive) on pins 1, 2, 3, and 6.

Connecting an NBX Figure 8 illustrates how to connect an NBX Business Telephone, using the Business Telephone power splitter cable (3C10223: 12 pack). Follow these steps:

1Before you attach any other cable to the female RJ45 connector on the power splitter, insert the power splitter power plug into the power receptacle on the telephone.

2Plug the male RJ45 connector on the power splitter into the RJ45 receptacle on the telephone.

3Using Category 5 cable that has been checked for continuity on all eight wires, connect an EPS output port (a port on the upper row of connectors) to the data jack closest to the telephone.

This connection may involve multiple segments such as the patch panel and premises cabling shown in Figure 8. The total length of the connection path should not exceed 100 meters.

See Figure 4 in Chapter 1 for a sample topology using the EPS and the NBX 100 Business Telephone.
